Stormwater Pond & Outfall Leak Survey in Nanaimo, BC
Detention ponds, retention facilities, outfalls, and culverts surveyed for exfiltration, berm seepage, and bypass flow — the drainage infrastructure nobody can see failing until something downstream floods or erodes. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Nanaimo and the Vancouver Island region — since 1999 as BC's leak detection specialists.

Flying Nanaimo: local context
Harbour city with hospital-area densification; YCD-adjacent operations under authorization.
Local property profile: Harbour-city mix of heritage districts, mid-century suburbs, and rapid hospital-area densification.
Ground conditions: Standard till performance at surface, but Nanaimo's defining subsurface feature is its coal-mine legacy: old workings and shafts underlie several neighbourhoods, making void detection a local specialty.
Typical stormwater pond & outfall leak survey work around Nanaimo
- Mid-rise envelope thermography

- Outfall and culvert condition screening
How the Nanaimo survey runs
- 1
Facility review
Design drawings establish what the pond is supposed to do — normal water level, outlet structure behaviour, berm geometry. Deviations from design are what the survey hunts.
- 2
Aerial mapping flight
Thermal plus high-resolution visual covers the pond, berms, inlet and outlet works, and the downstream path. Water level, wetted perimeter, and berm condition are captured in one georeferenced dataset.
- 3
Anomaly analysis
Seepage expression on berm faces, thermally distinct inflows that should not exist, scour at outfalls, and saturated zones beyond the design footprint are flagged and ranked.
- 4
Condition report
A facility plan with annotated findings — formatted for public-works files, development acceptance packages, or the consultant's stormwater management review.
Nanaimo questions, answered
What goes wrong with stormwater ponds that this finds?
The common failures are quiet ones: berms seeping through rodent burrows or poorly compacted lifts, liners leaking so the pond never holds design volume, outlets short-circuiting, and exfiltration saturating ground beyond the facility. All express thermally or visually at the surface — and all are far cheaper to fix before a major storm finds them first.
Why survey a developer-built pond before municipal acceptance?
Because once a municipality accepts the facility, its defects become the public's. An aerial condition survey at turnover documents berm condition, water behaviour, and any seepage objectively — either confirming the asset is sound or putting deficiencies on the record while the developer still owns them.
Can you inspect outfalls and culverts too?
The approaches, headwalls, scour patterns, and surrounding ground — yes, and that screening tells you which structures justify CCTV or confined-space entry. We pair naturally with our ground-based CCTV inspection service for the inside-the-pipe half.
Can you legally fly drone leak surveys in Nanaimo?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Nanaimo flights run under whatever airspace authorizations the location requires. Harbour city with hospital-area densification; YCD-adjacent operations under authorization. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How do Nanaimo ground conditions affect what the survey reads?
Nanaimo ground is predominantly till and sandstone benches — with documented historic coal workings beneath parts of the city. Standard till performance at surface, but Nanaimo's defining subsurface feature is its coal-mine legacy: old workings and shafts underlie several neighbourhoods, making void detection a local specialty. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.
What does stormwater pond & outfall leak survey cost in Nanaimo?
Province-wide pricing — no regional premium for Nanaimo. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
